    MasterInject 1320 - Single component polyurethane injection resin for sealing of cracks in concrete

    How does MasterInject 1320 work?

    MasterInject 1320 is a single component hydrophilic injection resin which forms an impermeable flexible seal when injected into cracks in concrete.

    Where is MasterInject 1320 applied?

    • Permanent crack sealing of below ground structures such as tunnels, shafts, basements and underpasses.
    • Stopping of minor water seepage.
    • Can be injected after MasterInject 1335 in cracks where higher water flows occur.
    • Single use injection through MasterSeal 909 injection hoses

    What are the advantages of MasterInject 1320?

    • MasterInject 1320 is based on a moisture curing MDI Isocyanate and does not require the addition of a "reactor" to activate the material
    • The product cures to form a flexible and impermeable seal where further limited movement of the concrete is anticipated
    • It reacts under wet / damp conditions and foams upon contact with water
    • Good bonding to damp / wet surfaces
    • Permanent sealing effect
    • Low viscosity – allows penetration of fine cracks
    • Does not contain toxic TDI Isocyanate
    • Has a low shrinkage compared to standard TDI based injection sealing products
